IPC: B21B1/22
Filed: 1987-11-05
Abstract: PURPOSE:To improve the surface brightness and to prevent the production efficiency from dropping by performing a nonlubrication rolling treatment for a stainless steel hot rolled strip by a prescribed draft and using rolls having respective specific surface roughnesses in the final pass and passes before the final pass in cold rolling. CONSTITUTION:A nonlubrication rolling treatment with >5% draft is performed for a stainless steel hot rolled strip after the strip is subjected to intermediate annealing and pickling. In the succeeding cold rolling, the strip is rolled by a work roll having an average surface roughness Ra of <=0.25mum in the final pass and is rolled by a work roll having an average surface roughness Ra in the range of 0.4-0.7mum from a 1st pass to the pass one less than the final pass. By nonlublication preparatory rolling, the surface brightness is improved and seizing and generation of oil pits in passes before the final pass are prevented. The surface brightness is improved and the production efficiency is prevented from dropping because of preventing scratches from remaining in the final pass.

Title: Picture encoding device
Inventor: NAKAYA YUICHIRO
IPC: H04N19/51
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To simplify processing when a patch is a right angled triangle or a rectangle by utilizing a difference value of transformation functions between adjacent picture elements. SOLUTION: Affine transformation is adopted as a transformation function and movement compensating processing is executed by the use of a triangular patch. The coordinates of respective vertexes of a triangular patch S in the original picture of a current frame and the coordinates of corresponding points in the highly accurate reference pictures of respective vertexes are set up so as to satisfy two prescribed conditions by operating the directions of coordinate axes and the position of an origin. In this case, high approximation in the calculation of the transformation function using rear numbers is obtained by the coordinates p (x, y), q (x, y) of points in the highly accurate reference pictures corresponding to picture elements (x×mx, y×my) in the patch S in executing texture mapping. The luminance values of the picture elements located on the coordinates p (x, y), q (x, y) of the highly accurate reference picture are regarded as a predicted value of luminance on coordinates (x×mx, y×my).

IPC: E06B9/264
Filed: 1995-10-26
Abstract: PURPOSE: To reduce electric wiring work by controlling the vertical and opening/ closing movements of blinds, either integrally or individually, while aiming at each or all of zones. CONSTITUTION: When an all-zone key, an interlock key and a slat angle key in a zone controller 4 are operated, all blinds 11, 12...1n, 21, 22...2n, 31, 32...3n constituting all zones 1 to 3 become subjects for control and are interlocked with one another to adjust the angles of their slats by rotating the slats so that the tilted surfaces of the slats face inward. When a command signal including a set action identification code is received by a master blind from the zone controller 4, the microcomputer of a control portion outputs data about the current height and the slat angle of the blind to slave blinds on the basis of a signal from a height encoder and that from an angle encoder. The slave blinds are raised or lowered in accordance with these data so as to become equal in height and then in slat angle to the master.
